Problems that may be encountered during use and their solutions
unstable temperature jump
It is normal for a new T12 tip to experience temperature jumps when used for the first time. It needs to be aged for a while to be stable. Specific operation: first set the temperature at about 250°C to tin the head, then adjust the temperature to 350°C for 30 seconds, turn off the power and wait for it to cool down to room temperature, repeat the operation twice, and it will stabilize after slow use.
Even if the soldering iron is plugged in, it still prompts that the soldering iron tip is not found.
This phenomenon indicates that the contact between the soldering iron tip and the sleeve of the handle is not good. Check whether the soldering iron tip is fully inserted, and whether the shrapnel of the PCB bracket in the handle and the soldering iron tip are in normal contact.
The tip of the soldering iron is burning red
The T12 soldering iron tip is a composite tip that combines a heating core, a sensor, and a welding tip into one. When encountering this phenomenon, the sensor is out of control and is basically in an irreparable state.
Generally, you need to contact the after-sales service to send it back for repair.
Burning red, there is only one reason is that the sensor is short-circuited and cannot correctly perceive the real temperature of the tip of the soldering tip. When the temperature of the tip of the soldering iron tip reaches 520 degrees or more, the front part of the entire tip of the soldering iron will turn red. Use the method of elimination first, and directly replace the handle of a complete soldering iron to see if this situation still exists. If there is no problem, it means that the problem is the handle. Further check whether the sensor of the soldering iron handle is reversed. If the sensor is normal (this kind of screen temperature is generally 18°C, and the theoretical temperature is above 560°C, the soldering iron hair is red), and then check whether the six-pin socket and the five-pin socket are reversed. Whether the field effect tube is not burning well, and the handle sensor is welded backward. The handle wire is wrong (replace the handle to rule out this problem).
Soldering station error
1. The aviation connector is in poor contact, re-plug it.
2. The temperature wire of the thermocouple in the handle is weakly welded, and repair welding is enough.
3. There are burrs or foreign objects in the temperature measuring hole of the soldering iron tip, and the temperature sensing is abnormally lagging behind. Clean it and reinstall it.
